Solid-liquid separation negative pressure treatment equipment

Abstract

The invention discloses solid-liquid separation negative-pressure treatment equipment which comprises a rack, a filter bin, a negative-pressure bin, a rotating shaft driving device, a main shaft assembly and a filter cartridge; a sewage inlet and a solid scraper blade are arranged on the filter bin, and one side of the filter cartridge is matched with the solid scraper blade; the main shaft assembly comprises a main rotating shaft and a negative-pressure shaft, the main rotating shaft is matched with the rotating shaft driving device, one end of the negative-pressure shaft is located in the negative-pressure bin, the other end of the negative-pressure shaft penetrates into the filter cartridge to be connected with the main rotating shaft, and a water inlet is formed in the part of the negative-pressure shaft entering the filter cartridge; according to the scheme, sewage is filtered through the filter cartridge in the filter bin, the filter cartridge rotates, filtered solids are scrapedoff through the scraper blade, the sewage is subjected to negative-pressure extraction from the interior of the filter cartridge, and it is guaranteed that the extracted sewage is certainly subjectedto effective solid-liquid separation; the whole equipment can keep efficient, stable and continuous operation, the sewage treatment efficiency is high, the solid-liquid separation effect is good, andmanual repeated dismounting and washing are avoided.

Description

technical field [0001] The invention relates to solid-liquid separation negative pressure treatment equipment, which belongs to the technical field of garbage sewage treatment equipment. Background technique [0002] In the process of sewage treatment and purification, solid-liquid separation is required. Most of the conventional solid-liquid separation methods are to filter the sewage through filter components such as filter screens; but in the actual filtration process, it often occurs that sewage and filtered solids cannot be effectively In the case of separation, multiple filtrations are required, which reduces the processing efficiency; and the accumulation of solids will block the filter screen, which requires frequent manual disassembly and cleaning, which is a waste of manpower. Contents of the invention [0003] The object of the present invention is to provide a solid-liquid separation negative pressure treatment device in order to overcome the deficiencies of th...
